D escription High-Precision Aerial LiDAR System The DJI Zenmuse L2 is an integrated geospatial data acquisition system. It combines frame LiDAR technology, a high-accuracy IMU system, and a 4/3 CMOS RGB mapping camera. This system is designed to provide precise and efficient data collection capabilities when used with DJI flight platforms, particularly when integrated with DJI Terra software. The Zenmuse L2 offers high vertical and horizontal accuracy of 4 cm and 5 cm, respectively, covering a substantial 2.5 km² area in a single flight. It features exceptional penetration capabilities, smaller laser spots than its predecessor, and supports up to 5 returns. With a frame-based design and improved IMU system, it ensures high-precision mapping, making it suitable for various applications, including land surveying, electricity management, forestry, infrastructure management, and more. Users can easily process point cloud data and achieve accurate geospatial results, enhancing overall operational efficiency. RGB Camera Maximum Returns System Accuracy Detection Range 20 MP, 4/3 CMOS 5 5 CM Horizontal, 4 CM Vertical (150m AGL) 250m @ 10% Reflectivity Comprehensive LiDAR Solution With its robust hardware support, the L2 system excels at conducting precise scans of intricate subjects over extended distances, facilitating faster point cloud acquisition. During operations, users can conveniently preview, playback, and process point cloud models on-site, accompanied by Task Quality Reports generated by DJI Terra. This holistic solution simplifies the process, enhancing overall efficiency and enabling users to achieve high-precision point cloud results with streamlined post-processing. ​ Elevated Precision Levels By combining GNSS technology with a highly accurate self-developed IMU, this solution achieves vertical accuracy of 4cm and horizontal accuracy of 5cm. Exceptional Operational Efficiency From the moment it's powered on, the L2 system swiftly collects both geospatial and RGB data, covering a wide 2.5km² area in a single flight. Intuitive User Experience In conjunction with the Matrice 350 RTK and DJI Terra, the L2 system provides a turnkey solution that is remarkably user-friendly, reducing the operational learning curve. Expanded Detection Range by 30% The L2 system offers impressive detection capabilities, ranging from 250 meters at 10% reflectivity and 100 klx, all the way to 450 meters at 50% reflectivity with 0 klx. This extended range also enables a typical operational altitude increase of up to 120 meters, significantly enhancing operational safety and efficiency. Reduced Laser Spot Size, Enhanced Point Cloud Density Featuring a smaller spot size of 4×12 cm @100m, which is merely one-fifth the size of its predecessor, the L2 not only detects smaller objects with greater detail but also penetrates denser vegetation, resulting in more accurate digital elevation models (DEM). Support 5 Returns In densely vegetated environments, the L2 can effectively capture more ground points concealed beneath foliage Point Cloud Rate: 240,000 pts/s Operating in both single and multiple return modes, the L2 can achieve a maximum point cloud emission rate of 240,000 points per second, allowing for the acquisition of a more extensive point cloud dataset in a given timeframe. Two Versatile Scanning Modes The L2 system provides support for two scanning modes, catering to users' specific task requirements. In repetitive scanning mode, L2's LiDAR technology delivers uniform and precise point clouds, meeting the demands of high-precision mapping. In non-repetitive scanning mode, it offers enhanced penetration for capturing structural information, making it well-suited for applications such as power line inspection, forestry surveying, and other similar scenarios. Innovative Frame-Based Design The frame-based design results in an effective point cloud data rate of up to 100%, further complemented by a three-axis gimbal, opening up new possibilities for various surveying scenarios.
